Idea 1: involves cat but I'm sure HTS rules won't let me post the details and SPCA members might get upset.
Idea 2: I was doing some renovation work in a retirement village recently and the guys were there fitting new screen doors. These has a material that looked like conventional weak screen material, but was actually very strong, a very open weave of fine plastic coated steel wire. I suggested it looked strong enough to be almost a security door and the installer whacked it very hard with his palm and it didn't even look like being damaged. I'm sure a cat's claws couldn't damage it.
I didn't get a brand name, but surely something similar would be available in the US.
